I've had this for about a week now. Most of the points lost in this review come from the assembly instructions. The manual has a couple of mistakes that range from annoying to a work stopper. In step 4, you're supposed to mount the motor with the threaded ends of the bolts up -- however, the next two photos of that step show the bolt heads up. Then in a following photo, the bolts have magically re-aligned themselves.In step 5, you're supposed to mount the motor pulley. However, the pulley has a slot which in my case wasn't completely finished. I had to take a file and complete cutting the slot.What stopped me for a couple of days was wiring the motor as in step 15. First, the picture in the manual bears absolutely no resemblance to mine. It does state to contact tech support for a new wiring diagram. You're going to need the catalog, because the tech support number in the manual is out-dated. I e-mailed tech support and they sent me the wrong diagram - twice. Finally they told me it didn't matter which wire of the cord went to which wire on the motor. Thankfully I knew enough to know the green wire was the ground. I'm guessing that many buyers of this item will probably know more about wiring 110v motors than I do and this may not be that big of a problem to them.Lastly, belt alignment didn't go too well. The sanding belt runs on three wheels, top, bottom and back. The manual tells how to align the top and back -- and that went OK. However, the bottom wheel wouldn't align. The belt rubbed against the body of the sander. I called tech support (using the catalog number) for help. The tech admitted that the arm was a bit flimsy when I told him that twisting the arm seemed to help the alignment. While he couldn't tell me to actually bend the arm, I got the impression that's what was needed. I grabbed a 18" adjustable wrench and twisted the upright arm just enough for the bottom wheel to start tracking.Once all that was done, it seems to work fine. The belt guards are a bit noisy -- you have to nudge them now and then to dampen some noisy vibrations. I will also have to remember to keep an eye on the lower wheel tracking in case the arm returns to its original position.I've used it for some light sanding so far and that part works OK. The motor seems to have plenty of oomph for the size of the machine. The sanding tables are OK, although adjustments are primitive. There were no missing parts, and other than the minor assembly problems (electrical not so minor) it went together easily. However, Grizzly needs to spend a few bucks to strengthen the upright arm and revise their instruction book to make this a much better tool. I'm going to try to figure out a way to brace the arm - perhaps bolting some stiffer angle iron to it will help.My conclusion is that it's OK, probably worth the price, but not better than just OK.

The adjustments and set screws are almost useless, and the pieces that are cast were poorly finished. I got it set up and it is useable, but adjusting it and changing belts is WAY more trouble that it should be. Keeping the table at exactly 90 degrees is about impossible.

If you want a light duty unit this will work. I bought it for knifemaking, and I"ll have to replace it before I can do any serious work.
